RIDE CONTROL PRESSURE EQUALIZATION TIME ADJUSTMENT
0017 00
N OT E
When ride control system is activated and pressu e between ride control accumulator and lift cyl-
r
inders is not equal, lift arms will raise or drop depending on load.
Pressure equalization time for ride control is transition between OFF and ON. This transition is
time required to equalize pressure between ride control accumulator and lift cylinders.
Ride control system changes fromOFF to ON more quickly when lower value is entered. Like-
wise, transition of ride control system from OFF to ON is slower when higher value is entered.
For example, setting time to greater value will result in more time to balance ride control accumu-
lator with lift cylinders. Now, more time is required for ride control system to go from OFF to ON
after switch is placed in ON position. Ride control system requires more time to equalize when
hydraulic oil is cold.
Factory setting of pressure equalization time is 3 seconds. Range of 1 to 5 seconds is recom-
mended.
